    Secondary School Students and Caffeine: Consumption Habits, Motivations, and Experiences.
    (MDPI (Basel, Switzerland), 2023-02-17) Turner S; Ali A; Wham C; Rutherfurd-Markwick K; Cornelis M; Tauler P
    Adolescents may be particularly vulnerable to the effects of caffeine due to a lack of tolerance, their small size, changing brain physiology, and increasing independence. Concerns about adolescent caffeine consumption relate to potentially serious physiological and psychological effects following consumption. Motivations driving caffeine intake are not well understood among adolescents but are important to understand to reduce harmful behavioural patterns. This study explored caffeine consumption habits (sources, amount, frequency) of New Zealand adolescents; and factors motivating caffeine consumption and avoidance. The previously validated caffeine consumption habits questionnaire (CaffCo) was completed by 216 participants (15-18 years), with most (94.9%) consuming at least one caffeinated product daily. Chocolate, coffee, tea, and kola drinks were the most consumed sources. The median caffeine intake was 68 mg·day-1. Gender (boy) and being employed influenced the source, but not the quantity of caffeine consumed. One-fifth (21.2%) of adolescents consumed more than the recommended European Food Safety Authority (EFSA) safe level (3 mg·kg-1·day-1). Taste, energy, and temperature were the main motivators for consumption, and increased energy, excitement, restlessness, and sleep disturbances were reported effects following caffeine consumption. This study provides information on caffeinated product consumption among New Zealand adolescents, some of whom consumed caffeine above the EFSA safe level. Public health initiatives directed at adolescents may be important to reduce potential caffeine-related harm.

    Development of a casual video game (Match Emoji) with psychological well-being concepts for young adolescents
    (SAGE Publications, 2021-10-04) Pine R; Te Morenga L; Olson M; Fleming T
    Digital interventions for mental health and well-being have been shown to be effective in trials, yet uptake and retention in real-world settings are often disappointing. A more significant impact may be achieved by building interventions that are closer to how target groups use technology to support their own psychological well-being. Casual video games may be poised to offer an opportunity in this area as they are a highly popular activity among young people. We propose that mental health content can be integrated into the explicit content and the implicit processes used in casual video games. In this paper, we describe the design and core processes of Match Emoji, a casual video game designed to support the development of psychological well-being via gameplay and micro-messages. The iterative development of Match Emoji involved various phases, including a systematic review of the literature, consultation with target users, clinicians, game developers, and close reading of the literature. Expert collaboration was sought throughout the process to ensure gameplay and messages matched behaviour change and learning theories. An acceptability and feasibility study of Match Emoji will inform a randomised controlled trial in the future.

    Asthma inflammatory phenotypes on four continents: most asthma is non-eosinophilic
    (Oxford University Press on behalf of the International Epidemiological Association, 2023-04) Pembrey L; Brooks C; Mpairwe H; Figueiredo CA; Oviedo AY; Chico M; Ali H; Nambuya I; Tumwesige P; Robertson S; Rutter CE; van Veldhoven K; Ring S; Barreto ML; Cooper PJ; Henderson J; Cruz AA; Douwes J; Pearce N; WASP Study Group
    BACKGROUND: Most studies assessing pathophysiological heterogeneity in asthma have been conducted in high-income countries (HICs), with little known about the prevalence and characteristics of different asthma inflammatory phenotypes in low-and middle-income countries (LMICs). This study assessed sputum inflammatory phenotypes in five centres, in Brazil, Ecuador, Uganda, New Zealand (NZ) and the United Kingdom (UK). METHODS: We conducted a cross-sectional study of 998 asthmatics and 356 non-asthmatics in 2016-20. All centres studied children and adolescents (age range 8-20 years), except the UK centre which involved 26-27 year-olds. Information was collected using questionnaires, clinical characterization, blood and induced sputum. RESULTS: Of 623 asthmatics with sputum results, 39% (243) were classified as eosinophilic or mixed granulocytic, i.e. eosinophilic asthma (EA). Adjusted for age and sex, with NZ as baseline, the UK showed similar odds of EA (odds ratio 1.04, 95% confidence interval 0.37-2.94) with lower odds in the LMICs: Brazil (0.73, 0.42-1.27), Ecuador (0.40, 0.24-0.66) and Uganda (0.62, 0.37-1.04). Despite the low prevalence of neutrophilic asthma in most centres, sputum neutrophilia was increased in asthmatics and non-asthmatics in Uganda. CONCLUSIONS: This is the first time that sputum induction has been used to compare asthma inflammatory phenotypes in HICs and LMICs. Most cases were non-eosinophilic, including in settings where corticosteroid use was low. A lower prevalence of EA was observed in the LMICs than in the HICs. This has major implications for asthma prevention and management, and suggests that novel prevention strategies and therapies specifically targeting non-eosinophilic asthma are required globally.

    Making subject choices: Influences on adolescents' decision making
    (Adolescent Success, 2016) Poskitt JM; Bonney I
    Middle Years students are required to make critical educational decisions with respect to subject choices. These decisions occur in adolescence - a period of intense identity formation, strong emotions, living in the moment and peer affiliation - characteristics which may affect decision making. Subject choices either broaden or narrow future pathways, so what influences adolescent student decisionmaking? A case study research investigation at one middle school involved teachers, students and their parents/caregivers through the use of questionnaires, interviews and document analysis to reveal various influences. Significant others (family, friends, older students and subject teachers), website sources and course information booklets were among the most frequently cited influences, although there were gender, ethnic and year-level variations. Structural issues related to school resourcing and timetabling affected some students’ choices. Of concern was inadequate awareness of: subject information, subjects required for entry to particular tertiary courses or career options, how to access information or who to approach. The school careers’ advisor was rarely sought, and subject teachers sometimes had little knowledge of progression in their field or career options. Implications arise from the study about effective ways to support adolescents in making appropriate subject choices.
